Pole-Free vs. Minimum-Norm Right Inverse in Design of Minimum-Energy Perfect Control for Nonsquare State-Space Systems

摘要

In this paper a comparison of energy cost for different types of perfect control structures is presented. It is shown, that there is a possibility to improve the said control strategy for nonsquare LTI MIMO discrete-time state-space systems in terms of robustness through seeking of minimum control energy. It is remarkable, that simulation examples made in Matlab/Simulink environment confirm the potential of pole-free control design not only in the context of maximum-speed and maximum-accuracy properties, but, what is important, in terms of minimum energy behavior.
